Some people wait their whole lives to find their soul mates. But not Holly and Gerry. Childhood sweethearts, they could finish each other’s sentences. No one could ever imagine them without each other.
When Gerry dies, Holly is devastated. But Gerry has left her a bundle of notes, one for each month of her year, each signed 'PS, I Love You'.
As the notes are opened, the man who knows Holly better than anyone teaches her that life goes on. With some help from friends and family, Holly laughs, cries and finds that life is for living – but it helps if there's someone watching over you.
